I had the same issue but just followed the solution which was suggested in the error message. I've run the win8settick.bat as administrator and restart my computer and problem was solved. By the way, my operating system is Windows 10.

The bat file did not help in my configuration (Win 10 + TC31-Full-Setup.3.1.4022.4).
Windows required digitally signed driver for TwinCAT C++ "TODO: Add company name"
Also the service TcSysSrv is not installed.

I was just working on this issue and didn't see it solved. If after running the bat file, you still get the error check the master's address. If you haven't make sure your "compatible devices" drivers are all up to date.
